MuscleCo-contraction: Muscle pains usually starts with a specific muscle problem such as strain, overuse, or trauma. . It can occur from acute overuse, strain, or overstretching of a muscle that was previously weakened. Muscle co-contraction is a reflex protective response that is mediated through the cns. It results in muscle tightening (i.e., guarding) to protect the injured part.
